Gurova A. Age peculiarities of biorhytmic structure of functional activity of humen cardiovascular system

1. Object: Physiological characteristics and indexes of cardiovascular activity under the weekly monitoring. Goal: research of spectral content of biorhythms of systolic, diasystolic and arterial pressure and frequency of heart contractions of males of different age groups. Methods: monitoring of arterial pressure and frequency of heart contractions was held by the automatic digital devices MT-40 with the oscillometric method. Chronobiologic and statistic analyses of the research results were held by the computer software tools "Statistica", v.6.0. and "StatgraphicsTM". Results and innovation: the thesis first comprises the age alterations of the spectral content of human biorhythms by the example of arterial pressure and frequency of heart contractions in the wide frequency range by usage of common data evaluation method. The age alterations of stability of circadian rhythm of arterial pressure and frequency of heart contractions cycle by cycle at the individual level have been revealed. The time rowrequirements for the identical parametric characteristics of circadian rhythm obtaining have been identified and an importance of night measurements has been described. The aspect of acircadian dissemination of biorhythms of arterial pressure and frequency of heart contractions and an increase of arrthysmogene oscillations of arterial pressure at a later age stage have been substantiated. The biological estimation of spectral content oscillations of the researched indexes at different age groups has been described. Implementation: cardiology, gerontology, valeology and sports medicine.
